This was so out of character

This.
It was more of "make up is dumb, I can do it if I want"

She put herself above looking feminine. She told herself she can look good in make up if she wanted.

The IF is the whole point. Those bitches laughing at her was a hard reality is "no, you can't just slap make up on yourself and suddenly be beautiful."

But that wasn't the message, it was that trying to fit into the norm makes some people uncomfortable and that they should just be themselves instead.

She never cared about validation.

It's both. It absolutely is sending a message that even this tough bad ass girl is secretly made of porcelain.

She literally hates the idea of girliness. That doesn't automatically make her a lesbian you cretin.

>"The tough girl is actually a little delicate flower who wants to be pretty". That's a terrible message and doesn't fit with the rest of her character in the show.
That's stupid and wrong. It's not even the message. She suffered for placing too much importance on other people's opinions in that moment. That's not exactly an endorsement of that behavior.

No it wasn't she can be strong willed and still be a little insecure about her appearance

Toph was treated like a doll for most of her life, and probably heard that she was beautiful from her parents and everyone working on or visiting the estate.

She probably thought those girls were being brutally truthful and that everyone before was just lying to her. She didn’t realize that Katara, a sea prune sucker who grew up in an igloo, made her look like a painted whore.

autists feel emotions, they're just shit tier at recognizing the outward signs of emotions in others
it's sociopaths who lack the capacity for many emotions, but ironically they tend to be decent at recognizing emotions in others

>along with her melodramatic speech about being blind and not caring about appearances.

It was like two lines of dialogue. Stop exaggerating.

Toph can tell when people are lying. She likely has been called pretty before, but there are some latent self esteem issues from not being able to see it for yourself. I mean, even real life pretty girls with perfect vision are insecure about their looks. Katara does have horrible taste in cosmetics though.

Literally how is it out of character, she doesn't want to open herself up to things based on beauty and appearance, vanity, because it's one of the few areas where she's unsure and lacks great confidence, getting called out by the girls just plays further into that - there's nothing wrong with the episode or writing
